Can you post the model number please.
Thats just the range of dryer. If you open the door there will be a sticker on the inside and it will start with E-nr.
Ok looking at this that cover is a clip fit.
Get a butter knife or a flat screwdriver and insert it into the top of that cover in each corner and thre will be a clip you push with the screwdriver or knife.
Do this and at the same time pull it and it should pull out from the top and lift it out from the bottom.
Try that and see what happens.
No worries try agaon later and let me know how it goes. As looking in the service manual its just showing it clipped into place.
Sorry to hear you had trouble getting it off. But that's the only way you can do these is by the clips at the top.
